Salut, je viens d'installer xubuntu 18.04 sur un Acer Aspire récent équipé d'une carte wifi Qualcomm Atheros QCA6174 802.11ac. Tout va bien, sauf que j'ai pas de wifi. Quand j'ai eu le même problème après avoir installé xubuntu 16.04, on m'avait conseillé de taper les commandes suivantes :
rfkill list
sudo rfkill unblock wlan
Sauf que cette fois-ci, ça ne marche pas, booooohhhhh
Quelqu'un a-t-il une idée ? Merci d'avance !
Je vous donne les retours des commandes usuellement demandées dans ce cas :

J'observe que la commande nm-tool n'a pas été reconnue. Est-ce à dire que nm n'est plus le gestionnaire des réseaux wifi ?
